Screw feeder: Screw conveyors are one of the most common and simple way to perform a dosing. It can be used both in LIW and GIW, can have different sizes. The design of the powder inlet as well as the screw flight pitch is of importance to manage to perform a quick and precise dosing.
that the feed screw is continuously filled with material of a consistent bulk density. For instance, the feeder can have one feed screw with no agitator (Figure 2a), one or two screws with a vibrated trough or a pulsing flexiblewall hopper, one screw with a concentric agitator that operates at the same or a different speed (Figure 2b), or one screw with one or two agitators mounted above it ...
DPC Dosing Screw feeder. The DPCX series dosing systems are recommended for dosing powdery materials with mediumlow flow rates.
